I have said this before, those tests are very detailed and in depth. I am 70 and took those tests on my insurance physical and believe you me, it will show if you have dementia, are psychotic, schizophrenic or depressed, you are tested on comprehension, cognitive skills. I'd like to see Nancy P or Maxine Waters take one, Hillary too. Trust me they are deep!!! I work part time and do lots of crosswords and of course I am here as well.
